You might damage the bearings if you use the tonearm as a hammer! Otherwise, no!
Should the Tone Arm be Removed When Installing Cartridge?
I have a Linn Sondek LP12 with an Ekos SE tone arm. I've been told that a proper installation of a cartridge requires that the tone arm be removed to ensure no harm comes to the bearings in the tone arm. Is that an accurate and legitimate concern for my Linn, or any turntable?
